Ooh, good questions.
My third ever character on the server had an amazing death. I'd spent much of my time playing her as a very narcissistic and generally awful being, she wanted to get into magic, and naturally, being the terrible woman she was she hired a spy to look into one of her potential teachers so she might gain an edge. Eventually that teacher simply picked her up without such extreme measures. About three weeks in to being his student I get a bird from this spy, saying that the teacher had had an affair. My character now loyal to her teacher goes to kill him with an atronach, though instead leaves him inches from death. Then she receives a bird from her teacher to come home, where she is then clobbered over the head and interrogated, the spy double crossed her! She ended up being burned at the stake as a witch. It was very narratively satisfying to see the culmination of her mistakes end like that.
Hm, a character I've admired? Most of theblackbobross' characters invoke some form of admiration for how he plays them. Though, I think I like The Hierophant, he's got a very deep set of motivations, while being the right amount of downright terrifying for my tastes.
I have a few characters, and thus this is a terribly difficult question. All backstory I've ever had has been from rp, other than a few characters I made as adults. Though, I did end up pk'ing a character because she just had too much rp in one direction for a community I had fallen out of love with to change. So, I suppose I would have wanted to change Urza somewhat, she was always very pious, and that can get boring if you grow bored of whatever roleplay you're in, because they're so rigid. I'd probably have wanted her to have been more of a goon for a little longer and forged more connections with her kind.
I really like classic literature, I steal from it quite often when playing my favorite character. I've been obsessed with Bram Stoker's Dracula recently. Though most of the time my inspiration is just from acting, and getting in character, I let the narrative and the world take it's own course.
Aha! I'm obsessed with music, and spotify is fun, you can search through so much of it and find songs you've never heard before. I usually trawl its recommendations, when I make a character playlist I choose a few songs that fit, and then I look for thematically similar ones until I have something I like.
German might be my native language, but my mother is half English, so taught me British English from quite a young age, I also lived in England for 11 years, so that really helps.
